its great...but there's a SHITLOAD of dialog - like one huge interactive movie. combine that with your spaceship phobia then you probably wouldn't like it. best graphics i ever seen on a videogame tho. i like rpgs and space ships so it was cool.
but if you beat mass effect 1 it made changes within your mass effect 2 game, and now that i beat #2 its gonna carry over to mass effect 3. even the look of my custom created main character and such.
